I bought a Bird Buddy with a solar roof (extra accessory). This thing is so cool! It has a wifi camera that'll notify you when you have a visitor. It uses AI to recognize the species of bird (or in some cases other animals)! It sends you little digital postcards of the creatures via the Bird Buddy app.
Some specs:
5 megapixel camera and HD live stream
120 degree field of view
Built-in microphone (they just released an app update that lets you listen to the visiting birbs!)
Operating temps:
-5f to 120f (-20.5c to 48.5c) - so make sure you take the camera module inside in the winter if you live in a cold place and then also make sure you're not mounting this in direct sunlight.
